CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 15/931,880, filed on May 14, 2020, the entire contents of which are incorporated herein by reference in their entirety and owned by the assignee of the instant application.

FIELD OF THE INVENTION

The invention relates generally relates to technology for identifying and detecting coachable events for agents within a call center.

BACKGROUND OF THE INVENTION

Companies and/or organizations can have call centers for interacting with customers. The call centers typically include agents or representative (e.g., human or bot) that interact with customers. The interactions can be voice, audio, video, text, email, instant messaging and/or other electronic format exchanges. The interactions can be recorded, e.g., audio and/or video recorded, such that the interactions can be analyzed later.

Typically, the volume of interactions recorded can be as high as 200,000 per hour.

Some current systems exist which can determine behavior of agents based on the interaction data. For example, interaction data can be input to previously trained behavior models to determine which particular behaviors an agent (a subset of agents and/or all agents) in a call center exhibit during interactions. However, determining the behavior of agents without understanding events surrounding the behavior can result in an inability to fully understand the cause of the behavior and result in a lack of insight into how to change the behavior. For example, an agent's interactions can be determined to include the behaviors of indifference, friendly and/or appreciative. The events that caused the agent to exhibit the identified behaviors are unknown. Therefore, in current systems, while it typically is possible to coach the agent based on the behavior, e.g., by telling the agent to be less indifferent, current systems do not yield the ability to provide more useful agent coaching information.

Therefore, it can be desirable to improve interaction analysis systems to provide output that can allow particular events to be identified that are correlated to the behavior, to, for example improve agent coaching.

SUMMARY OF THE INVENTION

One advantage of the invention can include an ability to present a particular event that occurred as the likely cause of a behavior to coach agents. This allows supervisors to use modeled results across 100% of their interactions instead of random sampling. Additionally, the coaching analysis can be fully customized to each contact center.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention can be practiced without these specific details. In other instances, well-known methods, procedures, and components, modules, units and/or circuits have not been described in detail so as not to obscure the invention.

FIG. 1 is a block diagram of a system 100 for providing coachable events for agents within a call center, according to an illustrative embodiment of the invention.

The system 100 includes a behavior scoring module 110, an event searching module 120, an event ranking module 130, an agent aggregation module 140, an example generation module 150, and a computer display 160.

The behavior scoring module 110 can receive a plurality of interactions. The plurality of interactions can include interaction data that was captured during interactions between agents and customers. The agents and our customers can be humans, virtual agents, and/or bots in any combination. The interaction data can include a unique agent identifier, a unique customer identifier, a unique interaction identifier, content of the interaction (e.g., a portion or all of the recorded conversation (video and/or audio), text, email chain, etc..) between the agent and the customer. The interaction data can also include date and/or time information. The interaction data can include other data as is known in the art that is typically captured by interaction systems.

The interaction data can be converted from one format to another. The interaction data can include more than one different format of data. For example, an interaction may include an audio recording and/or a text version of that conversation created by automatic spec recognition (ASR). Text versions of interactions may be stored and searched for.

The interaction data can be received via wired and wireless communication. The interaction data can be retrieved by the system 100 instead of received. In some embodiments, the interaction data is both retrieved and received from the system 100.

The behavior scoring module 110 can determine behavior score waveforms. A behavior score waveform can be a behavior score over time that is for a particular behavior. For example, behavior score waveforms can be determined for behaviors as follows: empathy, kindness, brevity, clarity, and compassion. The behaviors can be input by a user. The behaviors can be selected by a user from a database of stored behaviors. The behaviors can be previously defined behaviors or newly defined behaviors.

Each behavior score waveform can be based on the interaction data. The behavior score waveform can be determined for each behavior in a plurality of behaviors and for each interaction in the interaction data. If there are n behaviors and m interactions then j behavior score waveform can be determined, where n, m, and j are all integer values. A behavior score waveform can be determined for each unique combination of behaviors and waveforms, BW_(j)(b_(n),i_(m)). For example, assume there are three behaviors, b₁, b₂, b₃, and two interactions, i₁, i₂, then six behavior score waveforms can be determined as follows: BW₁(b₁, i₁), BW₂(b₁, i₂), BW₃(b₂, i₁), BW₄(b₂, i₂), BW₅(b₃, i₁), BW₆(b₃, i₂). In various embodiments, the number of behaviors and interactions are between 10 and hundreds of thousands.

Each behavior score waveform (BW_(j)) can be determined as follows:

BW _(j)=Σ_(i=1) ^(N) W(t _(j) −t _(i))S _(i)   EQN. 1

W(t)=exp(−at ²)   EQN. 2

where BW_(j) is the behavior score waveform, j is an index into a particular word, i is an index into a particular score at a particular time, where N is a total number of sentiment phrase entries, W(t) is a gaussian weighting window, t_(i) is a start time of element i, t_(j)−t_(i) is a time difference between the waveform time and the time of the phrase, a is a smoothing factor, and S_(i) is a sentiment score of element i. W(t_(j)−t_(i)) can be equal to 1.0 when the phrase occurs at the point in time, and become smaller the further away the phrase becomes to the point in time on the waveform. The sentiment score S_(i) can be determined based on a bag-of-phrase model that maps various phrases that can occur in a particular interaction to a score. Table 3 below shows an example of mapping phrases to a sentiment score.

TABLE 3 Phrase SentimentScore RIDICULOUS −2.3 TALK TO YOUR SUPERVISOR −1.3 . . . WONDERFUL 1.2 THANK YOU SO MUCH 1.4

As shown in Table 3, in this example, more negative phrases are mapped to lower scores while more positive phrases are mapped to higher scores. The transcripts (e.g., as generated by automatic speech recognition system based on audio recordings of interactions) can include a table of phrases with 1-4 sequences along with a start time and end time offset (e.g., as generated by the automatic speech recognition system). For example, for a transcript of “thank you for calling how may” where the start time in seconds for each word is 0, 0.3, 0.5, 0.6, 0.9, 1.0 and 1.2, respectively, can have 2, 3 and 4 word sequences with respective start time offsets and end time offsets, as shown below in Table 4.

TABLE 4 Phrase Start Time Offset End Time Offset THANK 0 0.3 THANK YOU 0 0.5 THANK YOU FOR 0 0.6 THANK YOU FOR CALLING 0 0.9 YOU 0.3 0.5 YOU FOR 0.3 0.6 YOU FOR CALLING 0.3 0.9 YOU FOR CALLING HOW 0.3 1.0 FOR 0.5 0.6 FOR CALLING 0.5 0.9 FOR CALLING HOW 0.5 1.0 FOR CALLING HOW MAY 0.5 1.2

During sentiment calculations for an individual call, an inner join of the sentiment table can be determined with the transcription data to produce sentiment results. For example, relevant sentiment phrase matches that can be used in future sentiment calculations can be determined and associated with their respective start time offset and end time offset, as shown in Table 5 below.

TABLE 5 Sentiment Start Time End Time Phrase Score Offset Offset SUPERVISOR −1.2 102.3 102.5 RIDICULOUS −2.3 120.3 120.6 I'M FRUSTRATED −1.0 130.2 131.0

A behavior score for each behavior score waveform can be determined. The behavior score can be the sum of sentiment score S_(i) from 1 to N, where N is the number of phrases in the transcript.

In some embodiments, the behavior score for each behavior score waveform is based on a corresponding behavior model. For example, assume behavior b₁ is pleasant, and behavior b₂ is distant, and there is one interaction i₁. In this example there are two behavior models, one for the behavior pleasant and one for the behavior distant. To determine a behavior score for behavior b₁, interaction i₁, the interaction data corresponding to interaction ii can be applied to the pleasant behavior model. To determine a behavior score for behavior b₂, interaction i₁, the interaction data corresponding to interaction i₁ can be applied to the distant behavior model. The behavior models can be models trained via a neural network (e.g., convolutional or recurrent neural networks). The behavior models can be input by a user.

In some embodiments, the behavior scoring module 110 identifies one or more durations within each behavior score waveform that are likely to include event data that influenced the behavior score. The identification can be based on determining durations of the behavior score waveform that are above a threshold. For example, turning to FIG. 2A, FIG. 2A is an example of a behavior score waveform (BW_(j)) 210 according to some embodiments of the invention. The behavior score waveform (BW_(k)) 210 has three windows, 220 a, 220 b, and 220 c that are above the threshold L_(thresh).

In some embodiments, the threshold L_(thresh) is based on the behavior type. For example, for a behavior that is pleasant, the threshold can be a larger value. In another example, for a behavior that is unpleasant, the threshold can be a lower value. In some embodiments, the threshold L_(thresh) can be input by a user. In some embodiments, if there are no durations that are above the threshold in the behavior score waveform, the threshold L_(thresh) can be lowered.

In some embodiments, the identification of the durations is based on determining durations of the behavior score waveform that are below the threshold L_(thresh).

In some embodiments, the durations are expanded. The durations can be expanded if the durations are close to each other such that they almost overlap (e.g., within a few milliseconds of each other or any predefined duration). In some embodiments, if no events are found within the durations within the thresholds, the duration can be expanded. The durations can be expanded based on a duration dilation time T_(D). The duration dilation time T_(D) can be input by a user.

In some embodiments, if expanding the duration leads to an overlap in time of two or more, the overlapped durations are merged.

For example, turning to FIG. 2B, FIG. 2B is an example of the behavior score waveform (BW_(j)) 210 of FIG. 2A with the identified durations dilated and merged, according to some embodiments of the invention. The three durations 220 a, 220 b, and 220 c are dilated by T_(D). For duration 220 a, the dilated duration is 230 a, for duration 220 b, the dilated duration is 230 b, and for duration 220 c, the dilated duration is 230 c. For the sake of simplicity, the duration T_(D) is only shown on FIG. 2B with respect to duration 220 a. Duration 220 b, and 220 c are each similarly dilated by T_(D) as is shown for 220 a. FIG. 2B shows that durations 220 b and 220 c overlap, and are merged into duration 240 a.

Each duration identified in a behavior score waveform can have properties as are shown below in Table 6.

TABLE 6 Name Type InteractionID Int BehaviorID Int StartOffset Int EndOffset Int Positive Bool where InteractionID is the particular interaction of the plurality of interactions for the behavior score waveform, BehaviorID is a unique identifier for the particular behavior for the behavior score waveform (e.g., behavior “pleasant” with a unique identifier of “1”), StartOffset is a time offset at an earliest time in an identified duration of a respective interaction, EndOffset is a time offset at a latest time in the identified duration of the respective, Positive is an indicator whether the duration was identified by finding durations where behavior score waveform is above the threshold or below the threshold.

In some embodiments, the behavior scoring waveform is a step function.

Turning back to FIG. 1, the event searching module 120 can receive the interaction data and locate events that occurred within the interaction data. For each event that is located, it can be associated with its corresponding interaction. For example, each event in the interaction data can have properties as are shown below in Table 7.

TABLE 7 Name Type InteractionID Int EventID Int StartOffset Int EndOffset Int Score Float where InteractionID is the particular interaction for the identified event, EventID is a unique identifier for the event, StartOffset is a number of milliseconds into an interaction where the identified event starts, EndOffset is a number of milliseconds into an interaction where the identified event starts, and score (e.g., floating point value) is a value that represents quality of the match.

Events can be located in the interaction data based on one or more queries. A set of queries (e.g., queries input by a user and/or received from another computing device) can be used to search the interaction data for events. Each time a query is satisfied, this can be identified as an event. For each event, the corresponding interaction that the event occurred within can be associated with the event (e.g., as shown above in Table 7).

Table 8 below shows an example of a query format used to identify events.

TABLE 8 Operator Description OR( ) True if any of subexpressions found AND_x( ) True if all of subexpressions found within x seconds BEFORE_x( ) True if first expression occurs before second expression AND( ) True if all subexpressions found in same file ANDNOT_x( ) True if first expression found, but not any following within x seconds ANDNOT( ) True if first expression found, but not any following within same file FIRST_x( ) True if expression found in first x seconds LAST_x( ) True if expression found in last x seconds NOTFIRST_x( ) True if expression not found in first x seconds NOTLAST_x( ) True if expression not found in last x seconds

The event searching module 120 can output all events identified in the interaction data.

The event ranking module 130 can receive as input the output of the behavior scoring module 110 (e.g., either behavior scores, behavior score waveforms, or one or more durations of behavior score waveforms) and/or can receive the output of identified events of the event searching module 120.

The event ranking module 130 can determine a behavior-event score based on received either behavior scores, behavior score waveforms, or one or more durations of behavior score waveforms, and/or identified events. For each unique combination of behavior and event, a behavior-event score can be determined. For example, assume that the event ranking module 130 receives two behaviors b₁ and b₂ and three events, e₁, e₂ and e₃, a behavior-event score can determined for b₁, e₁; b₁, e₂; b₁, e₃; b₂, e₁; b₂, e₂; and b₂, e₃.

The behavior-event score can indicate a relevancy of a particular event to a particular behavior. The behavior-event score can be determined by searching each of the behavior score waveforms for a particular behavior for one or more events. For example, for a behavior of “pleasant” having a unique identifier (e.g., behaviorID) of 1, all of the behavior score waveforms in the interaction data can be searched for having the event “pleasant” and a behavior-event score can be determined for each interaction that has the event “pleasant.” The one or more events can be input by the user.

The events can be identified by matching the one or more events input by the user with one more events in the behavior score waveforms for a particular behavior as shown below:

def Match(behaviorID,eventID,interactionID, positive): match = 0 for window in windows where behavior.InteractionID == interactionID and behavior.BehaviorID == behaviorID  behavior.Positive == positive: for result in results where result.InteractionId == interactionID and result.EventId == eventID: if result.StartOffset < window.EndOffset and window.StartOffset < result.EndOffset: match = 1 return match

Each match can be used to determine the following parameters as shown below in Table 9.

TABLE 9 Name Description N Number of interactions N_(b) Number of interactions that include a behavior duration where BehaviorID == b N_(be) Number of event matches where EventID == e occurs in duration whereBehaviorID == b N _(be) Number of event matches where EventID == e occurs outside of any BehaviorID == b N _(be) Number of interactions with neither behavior nor event N _(be) Number of interactions with behavior duration, but no event

Each behavior-event score, BEScore (b,e) can be determined as shown below in EQN. 3 and EQN. 4:

$\begin{matrix} {{{MutInf}\left( {b,e} \right)} = {{\frac{N_{be}}{N}\log_{2}\frac{NN_{be}}{\left( {N_{be} + N_{\overset{\_}{b}e}} \right)\left( {N_{be} + N_{b\overset{\_}{e}}} \right)}} + {\frac{N_{b\overset{\_}{e}}}{N}\log_{2}\frac{{NN}_{b\overset{\_}{e}}}{\left( {N_{b\overset{\_}{e}} + N_{\overset{\_}{b}\overset{\_}{e}}} \right)\left( {N_{be} + N_{b\overset{\_}{e}}} \right)}} + {\frac{N_{\overset{\_}{b}e}}{N}\log_{2}\frac{{NN}_{\overset{\_}{b}e}}{\left( {N_{be} + N_{\overset{\_}{b}e}} \right)\left( {N_{\overset{\_}{b}e} + N_{\overset{\_}{b}\overset{\_}{e}}} \right)}} + {\frac{N_{\overset{\_}{be}}}{N}\log_{2}\frac{NN_{\overset{\_}{be}}}{\left( {N_{b\overset{\_}{e}} + N_{\overset{\_}{b}\overset{\_}{e}}} \right)\left( {N_{\overset{\_}{b}e} + N_{\overset{\_}{b}\overset{\_}{e}}} \right)}}}} & {{EQN}.\mspace{14mu} 3} \\ {{{BEScore}\left( {b,\ e} \right)} = {{{MutInf}\left( {b,e} \right)}*{{sign}\left( {\frac{N_{be}}{N_{be} + N_{b\overset{\_}{e}}} - \frac{N_{\overset{\_}{b}e}}{N_{\overset{\_}{b}e} + N_{\overset{\_}{b}\overset{\_}{e}}}} \right)}}} & {{EQN}.\mspace{14mu} 4} \end{matrix}$

In some embodiments, the behavior-event score is determined based on a correlation, or phi coefficient, for example, as shown below in EQN. 5.

$\begin{matrix} {{{corr}\left( {b,e} \right)} = \frac{{N_{be}N_{\overset{\_}{be}}} - {N_{b\overset{\_}{e}}N_{\overset{\_}{b}e}}}{\sqrt{N_{b}N_{\overset{\_}{b}}N_{\overset{\_}{e}}N_{e}}}} & {{EQN}.\; 5} \end{matrix}$

The behavior-event scores can be used to create a behavior-event score record for each unique combination of behavior and event, for example, as shown below in Table 10.

TABLE 10 Name Type EventID Int BehaviorID Int Positive Bool Behavior-Event Score Float

In some embodiments, a predefined number of top behavior-event scores are presented to a user. In some embodiments, the user overrides a high behavior-event score (e.g., the association of a behavior with an event). For example, if the event contraindicates the behavior.

In some embodiments, filtering is performed on the behavior-event scores. The filtering can be done based on the behavior-event score meeting a threshold, the duration in the behavior score waveform including a particular event, or any combination thereof. The filtering can be done as follows:

def KeepEvent(event, behavior, globalScoreThreshold): // Check if match occurs with positive or negative matchPos = Match(behavior.behaviorID, event.eventID, event.interactionID, True) matchNeg = Match(behavior.behaviorID, event.eventID, event.interactionID, False) if matchPos or matchNeg: // Get the event ranking for relevant behavior direction (matchPos) eventRanking = rankings where ranking.EventID == event.EventID and ranking.BehaviorID == behavior.BehaviorID and ranking.Positive = matchPos return eventRanking.Score > globalScoreThreshold else: return False

The filtered behavior-event scores can be recorded as shown below in Table 11.

TABLE 11 Name Type InteractionID Int EventID Int BehaviorID Int StartOffset Int EndOffset Int Behavior-Event Score Float

The agent aggregation module 140 can receive as input, output from the behavior scoring module 110, of behaviors scores, behavior score waveforms and/or the interaction data. The interaction data can be used associate interactions to agents as shown, for example below in Table 12.

TABLE 12 Name Type InteractionID Int AgentID Int

In some embodiments, the agent aggregation module 140 normalizes behavior scores for each behavior, for example, as shown in Table 13 below.

TABLE 13 Name Type BehaviorId Int AverageScore Float StandardDev Float LowerThreshold Float UpperThreshold Float

where AverageScore is an average of all of the behavior scores for a particular behavior, b, StandardDev is the mean and/or standard deviation of all of the behavior scores for the particular behavior b. LowerThreshold and UpperThreshold are equal to a fixed number of standard deviations (e.g., typically 1) above and below the AverageScore.

In some embodiments, the agent aggregation module 140 determines for each agent and behavior, a set of scores over a set of interactions. For each unique agent and behavior pair, all interactions with the same identifier can be grouped and the agent data can be aggregated as shown below in Table 14.

TABLE 14 Name Type AgentId Int BehaviorId Int AverageScore Float AverageScoreRank Int LowScorePercent Float LowScorePercentRank Int HighSorePercent Float HighScorePercentRank Int

where AverageScore is the mean of the behavior scores for the grouped interactions, LowScorePercent is the percentage of interactions with a score below a lower threshold, wherein the lower threshold can be one standard deviation below the average score and/or behavior dependent, HighScorePercent is the percentage of interactions with a score above an upper threshold, wherein the upper threshold can be one standard deviation above the average score and/or behavior dependent, AverageScoreRank is a ranking order between all agents in the interaction data, LowScorePercentRank is the percentage of interactions with a score below the lower threshold for all agents in the interaction data, LowScorePercentRank is the percentage of interactions with a score above the upper threshold for all agents in the interaction data.

The example generation module 150 can receive as input the output (e.g., the behavior-event scores and/or the filtered behavior-event scores) from the event ranking module 130. The example generation module 150 can locate particular event examples for an agent and/or behavior. Every event that is relevant can be collected based on its occurrence during a behavior by an agent, during a behavior window.

-   -   SELECT InteractionID, EventID, StartOffset, EndOffset,         Behavior-Event Score FROM FilteredBehaviorEventScores (Table 11)     -   JOIN BehaviorWindows (Table 6) on         FilteredBehaviorEventScores.BehaviorID=BehaviorWindows.BehaviorID     -   JOIN Events (Table 7) on         Events.EventID=FilteredBehaviorEventScores.EventID AND         (Events.InteractionID=BehaviorWindows.InteractionID) AND         (Events.StartOffset>=BehaviorWindows.StartOffset) AND         (Events.StartOffset<BehaviorWindows.EndOffset)     -   JOIN AgentData (Table 12) on         AgentData.InteractionID=BehaviorWindows.InteractionID     -   WHERE AgentData.AgentID=SelectedAgent AND         BehaviorWindows.BehaviorId=Selected Behavior

In some embodiments, these examples are presented to the user, being sorted descending by score. In some embodiments, these examples are grouped by InteractionID, and a score for each interaction ID is calculated by summing the behavior-event score for each result. These interactions can be presented in descending order of behavior-event score. This can allow for interactions with more events to rise to the top. On selecting an interaction, the user can be presented with a list of events within that interaction.

The output from the example generation module 150 and/or the agent aggregation module 140 can be transmitted to a display. In some embodiments, a table as shown below in Table 15 can be displayed.

TABLE 15 Behavior Acknowledge Listen Build Loyalty Empathy Actively Rapport Agent HScorePR LScorePR HScorePR LScorePR HScorePR LScorePR HScorePR LScorePR 65423 3 5 23 24 14 15 13 15 62844 25 23 2 4 12 13 16 19 . . .

In various embodiments, any of the interaction data, and/or data determined at the output or within intermediate steps of each of the modules in FIG. 1 can be transmitted to the display in various configurations.

In some embodiments, a supervisor can select any of the behaviors and obtain all events that can be used as example for coaching.

FIG. 3 is a flow chart of a method for providing coachable events for agents within a call center, according to an illustrative embodiment of the invention.

The method involves receiving a plurality of interactions that are based on recordings of interactions between customers and agents in the call center (Step 310). Each of the plurality of interactions can include interaction data, for example, as described above with respect to FIG. 1. The interaction data can be interaction data from a single call center or multiple call centers. The plurality of interactions can be received from a database where interaction data is stored, from other interaction systems, input by a user or any combination thereof. The interaction data can be a phonetic index and/or a transcript of a recording of an interaction.

The method also involves for each behavior in a plurality of behaviors and each interaction in the plurality of interactions determining a behavior score waveform (e.g., behavior score waveform 210 as described above in FIG. 2A) based on the respective interaction to create a plurality of behavior score waveforms (Step 320). The behavior score waveform can be determined based on machine learned behavior modules. The behavior score waveform can be determined based on one or more sentiment scores.

As described above with respect to FIG. 1, a plurality of behaviors can be input by a user, retrieved from memory, or any combination thereof. Each of the plurality behaviors can be any behavior of interest. For example, if the call center is a depression hotline, the plurality of behaviors can include empathy, understanding, and/or calmness. In another example, if the call center is for banking, the plurality of behaviors can include directness, clarity, and/or fairness.

The behavior score waveform can be determined as described above with respect to the behavior scoring module 110 of FIG. 1.

The method also involves for each behavior score waveform, identifying, by the computing device, one or more durations of the behavior score waveform (Step 330). The one or more durations can be durations within the behavior score waveform that likely include coachable events. The one or more durations can be determined as described above with respect to the event ranking module 130 of FIG. 1. In some embodiments, the one or more durations are dilated and/or merged, as described above.

The method also involves for each event in a plurality of events, identify the particular interaction within the plurality of interactions that the particular event occurred within and associating the particular event with the particular interaction (Step 340). The plurality of events can be input by a user, retrieved from memory, or any combination thereof. The interaction data can be searched to identify each of the plurality of events. Upon identifying each event in the interaction data, the particular interaction where the event occurred can be associated with the event. Associated the particular event with the particular interaction for each event in the plurality of events can be done as described above with respect to the event searching module 120 of FIG. 1.

The method also involves for each behavior score waveform, for each duration of the one or more durations (or dilated and or merged durations), determining a number of times each of the one or more events exist within each duration (Step 350). In some embodiments, the method also involves determining a number of times each of the one or more events exists outside of each duration.

In various embodiments, the method involves determining the number of times each of the one or more events exist within or outside of the behavior waveform (e.g., if there were no durations identified in the behavior score waveform). The number of times each of the one or more events exist within each duration can be done as described above with respect to the event ranking module 130 of FIG. 1.

The method also involves determining for each behavior and each event that exists in each behavior, a behavior-event score that indicates relevancy of a current event to the behavior based on the corresponding number of times the current event occurs within or outside of the duration (Step 360). As described above in FIG. 1, for each unique behavior and event pair from the plurality of behaviors and the plurality of events, a behavior-event score can be determined.

The method also involves displaying, by the computing device, for each behavior a ranked list of events with the behavior-event score scores (Step 370). The ranked list of events can be determined as described above in FIG. 1.
